Divers monitor a student-built autonomous underwater vehicle (AUV) as it navigates a course in a swimming pool during the Singapore Autonomous Underwater Vehicle Challenge.

“Designs of robots featured in SAUVC have been getting better over the decade,” said IEEE Senior Member Hari Vishnu. The competition is seeing AUVs that are faster, more robust and able to perform more tasks. The rules of the challenge have also changed to reflect the improved capabilities.

Student-built autonomous underwater vehicles compete in a series of tasks designed to mimic real ocean missions, including navigating through gates, locating targets, dropping objects into buckets and resurfacing, all without human control.

Many teams return year after year to refine their designs, and the experience often extends far beyond the pool. Organizers say many participants go on to careers in robotics, sensing and signal processing. Several teams have even launched startups after competing in the Singapore Autonomous Underwater Vehicle Challenge.

In a Singapore Swimming Pool, Young Engineers Test Robots for Earth’s Final Frontier

Building robots is hard. Building robots that can navigate complex underwater obstacles without a radio signal is even harder.

That’s the challenge that has drawn young engineers from more than 20 countries to the Singapore Autonomous Underwater Vehicle Challenge, or SAUVC, for more than a decade. Organized by the Singapore chapter of the IEEE Oceanic Engineering Society since 2013, the competition is one of only a few international contests focused on student-built autonomous underwater vehicles.

Each year, university and high school teams design and build robots that must complete underwater missions entirely on their own. Because radio communication does not work well underwater, the vehicles are fully pre-programmed before entering the pool, navigating obstacles and completing tasks without any physical connection to a controller. In recent years, organizers have introduced a limited communication challenge, where a base station sends a message partway through the mission for extra points, testing experimental underwater communication methods.

“Underwater robotics tends to be pretty complicated compared to land or aerial robotics,” said IEEE Senior Member Hari Vishnu.

The difficulty comes from several factors. Communication options underwater are limited or slow. Robots must move through a fully three-dimensional environment while coping with buoyancy, water pressure, potential leaks and poor visibility.

The missions themselves reflect real-world ocean operations. Robots may be required to pass through gates, locate targets, manipulate objects such as balls and buckets. Then they have to resurface at the end of a run. All of these skills relate directly to marine research and exploration.

The ocean covers about 70 percent of Earth’s surface, yet it remains one of the planet’s least explored frontiers. By challenging students to build autonomous underwater vehicles and test them in realistic scenarios, SAUVC has become a global training ground for the next generation of marine robotics engineers.
